UNITED STATES PATENT OFFICE.

SILAS H. RANDALL, OF W'YOMING, OHIO, ASSIGNOR OF ONE-HALF TO JAMES D. RANDALL, OF SAME PLACE.

HARNESS-MAKERS PRESS.

SPECIFICATION forming part of Letters Patent No. 465,679, dated June 18, 1889.

Application filed March 2,

To all whom it may concern:

Be it known that I, SILAS H. RANDALL, a citizen of the United States, residing at WVyoming, in the county of Hamilton and State of Ohio, have. invented certain new and useful Improvements in Harness-Makers Presses; and I do declare the following to be a full, clear and exact description of the invention, reference being had to the accompanying drawings, which form a part of this specification.

My invention comprises certain specific features in the construction of harness-makers presses, the details of the machine being here inafter more fully described, and pointed out in the claims.

In the annexed drawings, Figure 1 is a front elevation of my improved press, the main screw of the same being run down within the nut. Fig. 2 is a vertical section through the lower portion of the press. Fig. 3 is a plan of the rear clamping-bar detached from the bedplate. Fig. 4 is a horizontal section through a portion of the press. Fig. 5 is a side elevation of the complete press, the main screw being partially run up within the nut.

The base A, bed-plate B, overhanging arm 0, and back flange D are usually a single casting, the end of said arm having a nut c, traversed by the main screw E, which screw is provided with levers cc. Bearing against the front edge of plate B is a T-shaped casting F, whose opposite ends are provided with upwardy-projecting lugs ff and downwardly-projecting slotted lugs g g. Furthermore, the center of this casting has a depending flange G, bearing against the base A, as seen in Figs. 2 and 5.

b b are lugs similar to the slotted lugs g g, but depending from the rear edge of bed B, said lugs 12 g and b 9 being traversed by tiebolts H H, wherewith the casting F is immovably clamped to the front of said bed, the lugs f f of said casting being tapped to admit set-screws I I, whose inner ends bear against a detachable clamping-bar J. This bar has a vertical groovej, to admit the end of screw I, by which means longitudinal shifting of said bar is prevented.

J is a lateral extension of said bar, which extension has at its rear end a-lip j, that rests upon the bed B, soas to afford a firm bear- 1889. Serial No.301,754. (No model.)

ing for the bar without encroaching on the limited surface of said bed.

K is a rear clamping-bar, having a vertical groove 7r, a lateral extension K, and a lip is at the front end of said extension, said bar being adjusted by set-screws L L, tapped horizontally in the back of the press, the point of screw L entering the groove 70, as more clearly seen in Fig. 4.

Preparatory to using my press the bar K must be adjusted so as to bear against the rear edge of the strap or other piece of work, the center of which strap should be in line with the center of the main screw E. The other bar J is then adjusted to bear against the front edge of the strap, after which act the die is placed on the strap, and the screw E is forced down upon said die in the usual manner. The screw is then run up, the clampJ advanced to release the stamped work, and another strap is applied to the press and stamped, as above described, the clearance afforded by the overhanging arm 0 enabling the harness-maker to handle the strap or other piece of leather with the utmost facility.

I claim as my invention- 1. The combination, in a harness-makers press, of the main screw E, adj listing-screws I I, bed-plate B, and a jaw J, sliding upon it, which jaw has a lateral extension-J below the upper surface of said plate and a lip bearing against it, as herein described, and for the purpose stated.

2. The combination, in a harnessqnakers press, of the jaw J and its adj listing-screws I I, one of which, as 1, bears within the vertical groove j of said jaw, while the other screw Ibears against an ungrooved surface of the jaw, for the purpose described.

3. The combination, in a harness-makers press, of the bed-plate B, jaw J, sliding upon it, and fastened to said bed-plate the detachable plate F, having upwardly-proj ecting lugs f f to admit the adj listing-screws I I, that operate said jaw, as herein described, and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.

SILAS H. RANDALL.
